Abstract

Compounds of formula I < IMAGE > in which X is an iodine or bromine atom, R is a hydrogen atom, an acetyl, methoxyacetyl or trifluoro- acetyl group, m is an integer from 0 to 2, n is an integer from 0 to 4, the sum m + n being at least equal to 2, A1 and A2 independently of each other denote an aminoalcohol residue. These compounds can be employed in opacifying products.
